Allied Machine TAP2-25.40 Spade Drill Insert 1 in Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING TAP2-25.40 is a solid carbide spade drill insert designed for high-performance hole-making operations in steel workpieces. Part of the T-A Pro series, this insert seats in a Size 2 holder and features a 132-degree point angle optimized for entry stability and chip control in ferrous materials. The AM300 PVD coating provides enhanced wear resistance and thermal protection during high-speed drilling. At 0.1875 inches thick and 1 inch in diameter, this insert delivers consistent geometry and dimensional accuracy across production and job-shop applications. Licensed machinists and tooling technicians install this insert as a replaceable cutting element within modular spade drill body systems.

This insert is suited for drilling steel in both manual and CNC machining environments. The T-A Pro series is a modular spade drilling platform commonly used in horizontal and vertical machining centers, lathes with live tooling, and dedicated drill presses. Primary workpiece material classification is P-grade steel, covering mild steel, alloy steel, and similar ferrous stock. It is a direct replacement insert for Size 2 T-A Pro spade drill bodies where worn or chipped inserts need to be swapped without replacing the entire drill assembly. Sold individually per package with a minimum order quantity of 2 units.

Key Features

• Solid carbide construction for rigidity and wear life in steel cutting applications
• AM300 PVD coating provides thermal barrier and extended tool life at elevated cutting speeds
• 132-degree point angle promotes stable entry and reduces thrust force in steel
• 1-inch cutting diameter with 0.1875-inch insert thickness for consistent fitment in Size 2 bodies
• T-A Pro series modular design allows insert replacement without discarding the drill body
• P-grade material classification confirms suitability for mild and alloy steel workpieces

Compatibility

Designed for use with Size 2 T-A Pro series spade drill bodies. Consult the T-A Pro holder selection guide to confirm body compatibility before installation.

Installation Notes

Installation of spade drill inserts should be performed by a qualified machinist or tooling technician with the spindle fully stopped and machine power isolated. Seat the insert fully into the drill body pocket and torque the clamping screw to the holder manufacturer specification using a calibrated torque wrench. Inspect the seating surface and insert pocket for chips or debris before installation, as contamination can affect runout and insert retention. Follow all applicable shop safety procedures and machine guarding requirements during tool changes.
